Abstract:Sucheng District Cultural and Sports Center in Suqian city contains gymnasium, comprehensive gymnasium composed of youth activity center and exhibition hall, auditorium and cultural museum tower. The selection of structural system of each monomer building and the control of calculation indices under high seismic intensity were introduced as well as designs of the cross truss of the gymnasium roof and roof connection ribbon. The elastic analysis, plastic analysis and the calculation of the energy dissipation beam segment of the tower were conducted. The stress analysis on basement roof with big openings under the fortification earthquake was conducted. The results show that the selected structural system is reasonable, safe and reliable, and energy dissipation beam segment meets the energy dissipation requirements under the fortification and rare earthquakes respectively. The basement roof keeps elasticity under the fortification earthquake.

Keywords:Sucheng District Cultural and Sports Center in Suqian city; cross truss; elastic time-history; energy dissipation beam segment; slab stress
